Rear Axle Bearing Installation Page 2
STEP SEVEN: Once the axle is out, slide the brake disc off the axle. If there is a lot of rust, use some light sandpaper or steel wool to remove it. When done, clean the axle of any dust and debris thoroughly. You now need to remove the old bearings and seals from the carrier, so get a long piece of wood or something stronger to tap them out. To remove the left-side bearings and seals, place the piece of wood through the right-side until it's against the bearing, and tap the wood with a hammer.These too will probably be very hard to get out, so take your time; you don't want to damage the inside of the carrier. The seal will come out with the bearing eventually. Repeat this for the other side. When both bearings and seals are removed, clean the inside of the carrier and the sleeve of any rust or debris, like you did with the axle. After everything is clean, pack the carrier with plenty of grease.
STEP EIGHT: With the carrier full of grease and the sleeve inside the carrier, you can now install the new bearings. Push the bearing in by hand as much as you can. If it's snug and not going smoothly, tap the face of the bearing lightly using a block of wood and a hammer. Once fully inside, it will stop moving. Do the same with the other side, and then put grease all over the bearings themselves.
STEP NINE: Now take a seal and try to push it in by hand. Make sure there is grease on it and on the carrier where it sits. If it doesn't go in by hand, take a block of wood and gently tap it in until it's flush with the carrier. Take your time, you don't want to damage these. Repeat with other side.
STEP TEN: Slide your brake disc back on, and grease the axle really well. Gently begin inserting it into the carrier from the right side. Be careful not to damage the seals or bearings when installing. When it's in all the way, you can slide the sprocket with hub back on, and thread the two large nuts back on also. Tighten the inner nut until it's snug against the sprocket hub, without excess play when moving the axle back and forth from left to right. Tighten the outer nut against the first one firmly. Finally you can put your chain, brake caliper, and wheels back on. You're all set!
